L l 100 be Vapparent from the "detailed ldescription `The ends 1 3 of the compression member 10 andmanner of assembling the same; are slightly uptu'rned and Aeacli provided on l The inventionwconsists*ofstructural charitsupper surface with a transverse recess or acteristies'and relative arrangement of ele# Seat24, and upper shortperforated lflanges or ears Q5, 25, and also downwardly extending and perforated flanges Q6, 2G, as clearly shown in Figures 1 and 5.

27 is the tension member of the truss forming the bolster and is so arranged and'bent that its center section engages the bottom of the extension 19 of the central strut and its lateral upwardly inclined ends are seated between perforated sides Q1, 21, of the auxiliary struts :20, 20, and are held in place by the pins Q2, as clearly shown in Figures 1 and 4. The outer ends ofthe tension meinber Q7 beyond the auxiliary struts 20, 20, are passed between the lower perforated flanges 2G, 26, and turned bacl-z near its end and to- 'ards the center of the truck bolster and between the perforated ears 25, and pressed into the recess or seat Q1 and secured into this position by pins Q8, 2S, as shown in Figure 5 and at the right end of Figure 1.

Q9, 29, are chaing plates or guides secured by rivets or bolts 30, 30, to the perforated lower flanges QG, QG, as is commonly provided in this class of inventions.

Cooperating withthe above described truch bolster 10 is a body bolster 31 having rigidly attached to its under side by rivets $32. or other means, a downwardly projecting hollow male member 33 which is adapted to be seated and supported in the pocket or female bearing member 15 of truck bolster 10 and permitting said body bolster 31 to properly and easily swing through a small are, as required in this class of railway car appliances, and needs no further disclosure. The bottom and side walls of said hollow projecting male member 33 of the body'bolster 31 are prefer'- ably provided with openings 34, 3ft, through which may pass any grease or lubricant stored in said hollow male member 33,.said grease or lubricant passing into the center bearing 15 of the truck bolster 10 and between the contiguous Side walls and bottomsr of the pocket or female member 15 and male member 33, the grease being supplied to the hollow male member 33 through the opening 35 (see Figures 1 and 3) communicating with the interior of the body bolster 31.

From the foregoing disclosure, it will be seen that all the objects and advantages recited in the statement of invention have been fully and efficiently carried out and a fabricated trnssed cast or pressed steel truck bolster has been devised in which a recess, well, or female bearing member of a center bearing of any desired depth, and wholly between the compression and tension members of said bolster, can be effected without the use of a king pin cooperating with the body bol-- ster or in any way weakening said bolster, but on the contrary strengthening said bol ster with the use of a minimum of metal and cost. of manufacture.`
